Application, filed April 3, 1912. Serial No. 688,219.

To all whom Lt may' concern:

lie it knownthat l, Eismann Arnon, a citizen of the United States, and a resident of Cleveland, in the county of Cuyahoga and State of Ohio, have invented an improvement-in Router-Planes, ft which the following is a specification.

Ordinary router planes are provided with a bit or router proper adapted to cut grooves or depressions in the surtaceot woodwork. l provide a router plane stock with supplemental cutters and routers or' peculiar construction and arrangement, the same being placed opposite each other in vertical position and adapted tor lateral adjustment as required to cut grooves of ditlierent widths. These attachments are located in front ot the ordinary router bit or tool which may then be used to out and clean out the wood lying between the Smaller grooves made by the two attachments when adjusted a greater or less distance apart.

In the accompanying is a plan view of a router plane provided with my improved attachments.l Fig. 2 is a central longitudinal section on the line Q-Q of Fig. l. Fig. 3 is an enlarged side view of the combined cutting and routing device forming my invention proper. Fig. 4 is an end view of the same. Fig. 5 is an edge view. Fig. G is a side view.A

The router plane shown in Figs. and 2 comprises a stock formed ot two duplicate, longitudinal, parallel members l, l, which means of metal bars 2 having slots that receive clamp-screws 8. A routing tool proper d is held in a metal bridge 5 whose ends extend beyond the side edges of the parallel members 1. This tool 4 is provided with a notch adapted to receive the milled nut 6, which is applied to a vertical screw 7 that is secured by a clamp-screw S in the front portion of the bridge. apparent that, by rotating the nut 6, the tool 4 may be set higher or lower between the longitudinal members l.

My improved attachment is arranged in trout ot the routing tool 4 anu'is formed of a flat steel plate 9 having its-lower edge provided 'with two pendent cutters 10 and 11 and a router l2, the latter being arranged -drawing Figure l It is in rear of' said cutters and separated from them by a space 13, which provides an escape for the wood routed or removed by the bit 1 2.

As shown in Figs. 3 and 6, the cutter 10 is arranged in advance of the cutter 11, and, as shown in Fig. 5, the inner sides of these cutters are beveled to a tine edge, their outer sides being in the same plane with the body of the tool. The attachment comprising the tools constructed in duplicate as described are arranged vertical, parallel, and opposite, as shown in Fig. l, and each is adapted for vertical adjustment, it. being secured by a clamp-screw 14 to a slotted lug 15 forming a fixedl attachment of one of the parts l.v

It will now be apparent that when the router pla-ne or the frame of the same is reciprocated, the attachments described will cutinto the wood at the distance apart indicated in Fig. 5J and that the router 12 following, will take up and remove the wood lying between thecuts so made and at the same time smooth the bottom or" the groove which will thus be formed. 1When the two attachments are adjusted in contact, they will obviously form a single groove; but

-when adjusted apart from each other, as indicated in Fig.' 1, they will form two parallel grooves which are separated by the same space as intervenes the attachments. The routing tool #L forming an attachment of the plane proper may then be availed of to rout or remove the wood lying between the two parallel grooves thus made by my attach` ment.

What I claim is l. A, routing tool comprising a stock formed ot two members which are adjustable toward and from each other, means tor. securing them in such adjustment, and routing and cutting attachments secured thereto and comprising steel plates arranged opposite each other in parallel Vertical planes and having two cutters arranged infront, and

a router arranged 1n rear oi the same an adapted to cooperate therewith in the manner described. 2. The combination with an ordinary routinor tool, comprising opposite stock membes which are adjustable laterally toward grml from each other, and a planing or routwhereby said attachments are adapte@ to mg Jmol mounted adjustably between said form sega-rate parallel groevessubstantally members, of routing attachmenns comprising 'as cluescrlleedu steel plates arranged opposite each other BSMARK AYLOR. enel secured to he opposiie members of the Witnesses:
